Pronunciation: [ɹɪsˈɜːvjə] (IPA) 
The correct spelling of the word is "reservoir" /ˈrɛzərvwɑːr/. The first syllable is pronounced with the short 'e' sound /ɛ/ and the second syllable has a schwa /ə/ sound. The 'oir' at the end of the word is pronounced as a diphthong /wɑːr/. It's a common mistake to omit one of the 'r's and write 'reservior', which is incorrect. A reservoir is a large body of water, typically used for storing water or regulating its flow.
A reservoir is a man-made or natural artificial storage space or basin, often in the form of a large, naturally occurring or constructed body of water. It acts as a receptacle or container used for the accumulation and preservation of water, usually for the purpose of supplying water to communities, industries, or agriculture. Reservoirs are designed to hold significant quantities of water, providing a reliable and stable water supply in times of need. They play a crucial role in managing water resources and ensuring water availability.
Reservoirs can be found on various scales, ranging from small-sized local water bodies to massive lakes, often created by damming rivers or by capturing water in valleys and depressions. They are essential for a variety of purposes, including meeting domestic freshwater needs, generating hydropower, mitigating floods, maintaining ecological environments, and facilitating recreational activities such as swimming, boating, and fishing.
The design and construction of reservoirs involve careful planning and consideration of factors such as topography, climate, hydrology, and environmental impact. They may help regulate river flow or be filled through diversion from other water sources. Dams or barriers are erected to contain the water, forming the reservoir's boundaries and enabling controlled release or distribution when necessary. Proper management and maintenance are crucial to ensure the reservoir's sustainability and long-term functionality.
The word "reservoir" has its roots in the Latin language. It comes from the Latin word "reservare", which means "to reserve" or "to keep back". This Latin word is further derived from the combination of "re-" meaning "back" and "servare" meaning "to keep" or "to protect". Over time, from Latin, the word was absorbed into the Old French language as "reservoir" with a similar meaning. The English term "reservoir" entered the language in the late 17th century, referring to an artificial or natural storage place for water.
